ISLAMABAD, (MILLAT/APP): A recent study suggests that
drinking 30ml of concentrated blueberry juice daily can improve
brain function of elderly people.
According to researchers, the brain function in older people
tends to decline with age but a glass of blueberry juice can
improve brain blood flow, boost brain activation and some aspects
of working memory amongst older adults, a private news channel reported.
The team of researchers studied 26 healthy
adults, out of which 12 adults were given concentrated blueberry
juice providing the equivalent of 230g of blueberries once a day,
while 14 were given a placebo.
Those who consumed the blueberry supplement showed increased signs of blood flow to the brain and cognitive function, compared to the group that was given placebo.
Experts also indicated a significant improvement in working
memory.
The researchers pointed that blueberries are rich in
flavonoids, a component found abundantly in plants.
These flavonoids possess antioxidant and anti-inflammatory properties,
which prompt in causing these positive effects in the elderly.
Joanna Bowtell from the University of Exeter in Britain
said, “The study shows that with just 12 weeks of consuming 30ml
of concentrated blueberry juice every day, brain blood flow, brain
activation and some aspects of working memory were improved in
this group of healthy older adults.”
Researches conducted previously has already proved how an
higher fruit and vegetable intake reduces the risk of dementia. A
diet rich in plant-based foods also preserves the cognitive
function better in healthy older adults.
